In the next commit, I need the image name in lowercase because
output files are generally named in lowercase.
Unfortunately, TOOL_ADD_IMG takes the first argument in uppercase
since we generally use uppercase Make variables.
make_helpers/build_macros.mk provides 'uppercase' macro to convert
a string into uppercase, but 'lowercase' does not exist. We can
implement it if we like, but it would be more straightforward to
change the argument of TOOL_ADD_IMG.

Now FIP_ADD_IMG takes care of both fiptool and cert_create
symmetrically. Rename it so that it matches the behavior.

The build system supports generating two FIP images, fip and fwu_fip.
Accordingly, we have similar build macros.
FIP_ADD_PAYLOAD <--> FWU_FIP_ADD_PAYLOAD
CERT_ADD_CMD_OPT <--> FWU_CERT_ADD_CMD_OPT
FIP_ADD_IMG <--> FWU_FIP_ADD_IMG
The duplicated code increases the maintenance burden. Also, the build
rule of BL2U looks clumsy - we want to call MAKE_BL to compile it from
source files, but we want to put it in fwu_fip. We can not do it in a
single macro call since the current MAKE_BL does not support fwu_fip.
To refactor those in a clean way is to support one more argument to
specify the FIP prefix. If it is empty, the images are targeted to
fip, whereas if the argument is "FWU_", targeted to fwu_fip.
The build macros prefixed with FWU_ go away.

The function arm_validate_ns_entrypoint() validates a given non-secure
physical address. This function however specifically returns PSCI error
codes.
Non-secure physical address validation is potentially useful across ARM
platforms, even for non-PSCI use cases. Therefore make this function
common by returning 0 for success or -1 otherwise.
Having made the function common, make arm_validate_psci_entrypoint() a
wrapper around arm_validate_ns_entrypoint() which only translates return
value into PSCI error codes. This wrapper is now used where
arm_validate_ns_entrypoint() was currently used for PSCI entry point
validation.

mem_protect needs some kind of non-volatile memory because it has
to remember its state across reset and power down events.
The most suitable electronic part for this feature is a NVRAM
which should be only accesible from the secure world. Juno and
FVP lack such hardware and for this reason the MEM_PROTECT
functionality is implemented with Flash EEPROM memory on both
boards, even though this memory is accesible from the non-secure
world. This is done only to show a full implementation of
these PSCI features, but an actual system shouldn't use a
non-secure NVRAM to implement it.
The EL3 runtime software will write the mem_protect flag and BL2
will read and clear the memory ranges if enabled. It is done in
BL2 because it reduces the time that TF needs access to the full
non-secure memory.
The memory layout of both boards is defined using macros which
take different values in Juno and FVP platforms. Generic platform
helpers are added that use the platform specific macros to generate
a mem_region_t that is valid for the platform.

The CSS power management layer previously allowed to suspend system
power domain level via both PSCI CPU_SUSPEND and PSCI SYSTEM_SUSPEND
APIs. System suspend via PSCI CPU_SUSPEND was always problematic to
support because of issues with targeting wakeup interrupts to
suspended cores before the per-cpu GIC initialization is done. This
is not the case for PSCI SYSTEM_SUSPEND API because all the other
cores are expected to be offlined prior to issuing system suspend and
PSCI CPU_ON explicit calls will be made to power them on. Hence the Juno
platform used to downgrade the PSCI CPU_SUSPEND request for system
power domain level to cluster level by overriding the default
`plat_psci_pm_ops` exported by CSS layer.
Given the direction the new CSS platforms are evolving, it is best to
limit the system suspend only via PSCI SYSTEM_SUSPEND API for all
CSS platforms. This patch makes changes to allow system suspend
only via PSCI SYSTEM_SUSPEND API. The override of `plat_psci_ops`
for Juno is removed.

Replace all use of memset by zeromem when zeroing moderately-sized
structure by applying the following transformation:
memset(x, 0, sizeof(x)) => zeromem(x, sizeof(x))
As the Trusted Firmware is compiled with -ffreestanding, it forbids the
compiler from using __builtin_memset and forces it to generate calls to
the slow memset implementation. Zeromem is a near drop in replacement
for this use case, with a more efficient implementation on both AArch32
and AArch64.

Introduce zeromem_dczva function on AArch64 that can handle unaligned
addresses and make use of DC ZVA instruction to zero a whole block at a
time. This zeroing takes place directly in the cache to speed it up
without doing external memory access.
Remove the zeromem16 function on AArch64 and replace it with an alias to
zeromem. This zeromem16 function is now deprecated.
Remove the 16-bytes alignment constraint on __BSS_START__ in
firmware-design.md as it is now not mandatory anymore (it used to comply
with zeromem16 requirements).
Change the 16-bytes alignment constraints in SP min's linker script to a
8-bytes alignment constraint as the AArch32 zeromem implementation is now
more efficient on 8-bytes aligned addresses.
Introduce zero_normalmem and zeromem helpers in platform agnostic header
that are implemented this way:
* AArch32:
* zero_normalmem: zero using usual data access
* zeromem: alias for zero_normalmem
* AArch64:
* zero_normalmem: zero normal memory using DC ZVA instruction
(needs MMU enabled)
* zeromem: zero using usual data access
Usage guidelines: in most cases, zero_normalmem should be preferred.
There are 2 scenarios where zeromem (or memset) must be used instead:
* Code that must run with MMU disabled (which means all memory is
considered device memory for data accesses).
* Code that fills device memory with null bytes.
Optionally, the following rule can be applied if performance is
important:
* Code zeroing small areas (few bytes) that are not secrets should use
memset to take advantage of compiler optimizations.
Note: Code zeroing security-related critical information should use
zero_normalmem/zeromem instead of memset to avoid removal by
compilers' optimizations in some cases or misbehaving versions of GCC.

The capabilities exposed by the PSCI generic layer depends on the hooks
populated by the platform in `plat_arm_psci_pm_ops`. Currently ARM
Standard platforms statically define this structure. However, some
platforms may want to modify the hooks at runtime before registering
them with the generic layer.
This patch introduces a new ARM platform layer API

Consequently, 'plat_arm_psci_pm_ops' is no longer qualified as

The common topology description helper funtions and macros for

1. The `plat_get_power_domain_tree_desc()` definition is moved from

The shared memory region on ARM platforms contains the mailboxes and,
on Juno, the payload area for communication with the SCP. This shared
memory may be configured as normal memory or device memory at build
time by setting the platform flag 'PLAT_ARM_SHARED_RAM_CACHED' (on
Juno, the value of this flag is defined by 'MHU_PAYLOAD_CACHED').
When set as normal memory, the platform port performs the corresponding
cache maintenance operations. From a functional point of view, this is
the equivalent of setting the shared memory as device memory, so there
is no need to maintain both options.
This patch removes the option to specify the shared memory as normal
memory on ARM platforms. Shared memory is always treated as device
memory. Cache maintenance operations are no longer needed and have
been replaced by data memory barriers to guarantee that payload and
MHU are accessed in the right order.
